Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Understanding how deletion mutations in mitochondrial DNA contribute to aging can help delay age-related decline in ...

eLife is a non-profit organisation inspired by research funders and led by scientists. Our mission is to help scientists accelerate discovery by operating a platform for research communication that ...

Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter discovered a new property ...

Chromosomes are cellular structures that contain the genetic material. A chromosome is comprised of a single DNA molecule that may be either circular or linear. The full complement of a cell s ...

Researchers' initial understanding of meiosis was based upon careful observations of chromosome behavior using light microscopes. Then, in the 1950s, electron microscopy provided scientists with a ...

The theory of evolution, first articulated by Charles Darwin in the 19th century, has been the foundation of biological ...

In normal human cells, the nucleus contains 23 pairs of chromosomes that enclose the DNA. There are some natural processes that can damage DNA. For example, in chromothripsis, which occurs in some ...

In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like structures called chromosomes. The nucleus of one of your skin cells contains about two metres of DNA ...
